Appliances in the USA are designed to work on 110-120 V, whereas appliances in Europe operate on 220-240 V. What would happen if you tried to use a European electric shaver in this country?
A) It would probably work as well as it does in Europe, since it is the current rating, not the voltage rating, that matters.
B) It would barely work (or maybe not work at all), since the voltage here is too low to push enough current through the device.
C) It would probably overheat and burn up before very long.
D) This question cannot be answered without knowing the frequency used in Europe and in the USA, since this is the parameter that matters most in any electrical device that operates on alternating current.
E) It would probably work as well as it does in Europe, since it is the power rating, not the voltage rating, that matters.

European appliances are designed for higher voltage levels (220-240 V), so using them in the USA, where the standard voltage is 110-120 V, would result in insufficient power for the device to operate properly.
